In short: Marie Thérèse Louise of Savoy, the Princesse de Lamballe, was the most devoted friend of Marie Antoinette. Despite warnings of mortal danger, she abandoned safety in England to return to the chaos of the French Revolution, ultimately sacrificing her life to remain by the queen's side until the very end.

Born in Turin in 1749, Marie Thérèse was a member of the House of Savoy. Her marriage at 17 to the heir of the massive Penthièvre fortune ended in widowhood just one year later. Rather than retreating to a convent, she became a central figure at the French court, eventually serving as the Superintendent of the Queen's Household. This role, vacant for thirty years, granted her immense influence and a salary of 50,000 crowns, making her a lightning rod for public resentment and accusations of greed.

Her relationship with Marie Antoinette was profound, though it fluctuated as other favorites, like the Duchesse de Polignac, vied for the queen's attention. Despite her reserved nature and frequent bouts of fainting, Marie Thérèse remained a steadfast ally. During the escalating tensions of the French Revolution, she transformed her apartments at the Tuileries Palace into a hub for royalist activity, even managing a network of informers to vet the loyalty of the household staff. Her salon became a clandestine meeting place for the queen and political figures like Mirabeau.

When the royal family attempted to flee in June 1791, Marie Thérèse was left in the dark, only learning of the escape after the fact. She fled to England and the Austrian Netherlands, but the call of duty proved stronger than the instinct for survival. Despite writing her will in anticipation of her death, she returned to Paris in November 1791. She stood by the queen during the violent mob invasion of the Tuileries in June 1792 and accompanied the royal family to the Legislative Assembly. By August 1792, she was imprisoned at La Force, where her unwavering loyalty finally met its tragic conclusion during the September massacres.
